Crash with mods

[Sio]

Hi, I'm Simon and I have a problem, 

I used to have like 40 mods at a time and run them, no problem all good, 

Now randomly I'd doesn't work anymore, it crash if I use a particular mod (r7 and soyuz tma above the sky) and after crashing with that mod I can no longer play without crashing, every single mod makes me crash... Anyway I have ksp 1.6.1 and I used to have rss/ro mods and all the suggested mods... And yes I was using soyuz mod even through it's out of date... But it used to work so why isn't it still Woking??

Hi. Please publish your full KSP.log and if you know how, the Module Manager cache files (configcache, etc).

There's a good chance I recognize some already known unholy interaction between modules and help you.

You didn't say how you installed KSP.  If you have it from Steam, it may have updated and you may not be running 1.6.1.  I copy the pristine install out of the Steam directory and then copy it again to mod.  That way I control what version of KSP I run.  As well, check the link in my signature for troubleshooting info and how to find the logs.
